Abstract:The size distribution of particles containing benzo-(a)-pyrene was measured in a polluted part of Budapest. Particulate matter was collected and fractioned by a cascade impactor backed up by a glass fiber filter to capture unimpacted particles. The benzo(a)pyrene content of samples was determined with thin layer chromatography followed by absorption spectrofotometry. The results of three series of measurements are briefly presented and discussed.
